I had the same progression except I got a Phidias before I ordered the REO Grand (black/black by the way)
When I first started to vape a month ago, I never thought I would be interested in a box mod. I was looking for a cigarette replacement and a box didn't fit the bill. However after just a short time, the box started to make sense and after I received my Phidias I TOTALLY got it. No more fooling around with carts/cartos foam filler and general mess. Now all I do is just make sure I have juice in the bottle and a charged battery and I'm good for 2 days. Going to a self juicing box mod was the best thing I could have done. Plus another benefit is that a box does not remind me of a cigarette which I feel is a good thing since I dont smoke anymore. Overall I feel it's a better experience and if I had known when I first started, I would have certainly started with a good box mod. It's just simple.
Excellent post, dude...congrats on quitting the cigs!! You really expressed the reason for a box mod just the way I felt it. Thanks!
